The axle housing is marked by the numeral 23, and the dilfer ential is designated at 24.' The clamps 22 engage the axle housing 23 and hold the axle housing on the frame 16, in a substantially horizontal position, as indicated in Figure 2,

" it being recalled that Figure 9, although useful as showing such details, represents a setup different from the one under consideration.

' The auxiliary frame 16 has a side bracket '25 to be seen in Figure 9, and on thisside bracket 25 is mounted a lock 26 (Figures 13 and 2). The lock 26 engages one end of the shaft or axle in the axle housing 23, and holds that end of the shaft 27 against rotation, it

being understood that the differential 24 forms an operative connection between the shaft 27 and the shaft 3, so that when the shaft 3 is driven from the engine 2, the shaft 27 will be driven also.

On that end of the shaft 27 which is remote from the lock 26 is mounted a pulley 28.

The numeral 29 indicates a conveyor frame, adapted to discharge into a grain bin 30, or any other place of storage. Supports 32 (Figuresl and 4) are mounted on the auxiliary frame 16 and on the beams 19. The supports 32 carry pivot members 31, and the pivot .members 31 are engaged with a retainer 33 that holds a hopper 34 on the rear end of the conveyor frame 29. By meansof the pivot members 31, the conveyor frame 29 is so mounted that it can be swung up and down at its forward end, either to accommodate the forward end of theconveyor frame to the place of discharge, or to accommodate the rear end of the conveyor frame to the lace of intake. The material which is to e conveyed and elevated may be discharged from a wagon 36 intothe'hopper34, by means of a tail board which is shown in F igure 1 of the drawings.

A rear shaft 37 is provided, and is carried bv adJustable bearings 38 mounted on the rear fehdof the conveyor'frame 29. On one end of the shaft 37 there is a pulley 39 driving a belt 40 engaged with the pulley 28 on the shaft 27. There are sprocket wheels on the shafts 41 and 37, and about the-sprocket wheels. (42) is engaged a belt conveyor 43. Below the forward end of the belt conveyor 43, an opening 44 is formed in the bottom of the conveyor frame 29, as shown in Figure 7. The opening 44 discharges into a chute 45 carried by the forward end of the frame 29, and the chute, in turn, discharges into the grain bin 30, as shown in Figure 1. Owing to the presence of the opening 44, the buckets on the belt conveyor 43 will not catch or clog as the belt conveyor passes around the foremost sprocket wheel 42, an observation which ,will be understood readily when Figure 7 per part of the standard 10. The flexible element 46 is wound about a drum 49 carried by a shaft 50 journaled in the main frame 5. The shaft 50 is operated by a handle 51. A pawl and ratchet mechanism 52 (Figure 2) prevents retrograde rotation of the shaft 50.

In practical operation, when the parts are arranged as shown in Figure 1, the material to be elevated moves from the wagon- 36 through the tail board 35 into the hopper 34, the material being carried along in the conveyor frame 29 by the conveyor 43, the material running out through the opening 44 of Figure 7 into the chute 45, the chute 45 de livering the material into the bin 30.

The drive for the belt conveyor 43 comprises the engine 2, the shaft 3, the difl'erential'24, the shaft 27, the pulley 28, the belt 40, the pulley 39, the shaft 37, and the sprocket wheel 42 on the shaft. 9

The operator can rotate the shaft 50 and the drum 49 by means of the handle 51, the flexible element 46 being reeled on the drum 49, or being paid ofi the drum, the forward end of the conveyor frame being raised and lowered. Generally, the intermediate portion of the conveyor frame rests on'the transverse bar 15 of the standard 10, but there is no reason why the conveyor frame cannot be raised from that position, the conveyor frame swinging upwardly with the pivot members 31 as a center of swinging movement. 7 I e v,Reference now is had to Figures 9 and 8, wherein a slight rearrangement of parts is shown. In Figures 8 and 9, the beams 19, the supports 32, the conveyor frame 29, the belt 40, and the pulley 28 are removed. The axle housing 23 is turned through an angle of ninety degrees from the horizontalposition of Figure 1, andstands vertically. The clamps 22 are shifted, one clamp being on the lower portion of the frame 16, and the other clamp being carried by a block 53 which is mounted'on the upper portion of the frame 16. The lock 26 which holds one end of the shaft 27 against rotation is placed on a top bracket 54 carried by the frame. The lower portion of the shaft 27 is journaled in a bearing 55 on the lower part of the frame 16.

horizontal buzz saw 56 is mounted by any suitable means on the lower end of the shaft 27, and may be used to cut into a standing tree 57, as shown in Figure 8 of thedrawings. 7

When the machine is set up as shown in Figures 10, 11, an-d 12, the axle housing 23 recarried by the lower part of the beams 19. 1

A saw guard 62 is mounted at each end on the table 59. A brace 66 is connected to the table 7 59 and hasits lower end, mounted on the rod 61. A spacer 63 is interposed between the adjacent legs of the saw table and the brace 66. Flexible elements 64 are connected to the forward portion of the table 59, one of the flexible elements 64 being connected to the frame 16, and the other of the flexible elements being connected to the end of the block 53. The flexible elements 64 limit the rearward swinging movement of the table under the impulse of springs '55 connected at their rear ends to one of the beams 19, and at their forward ends to the table. Considered as a sawing instrumentality, the mechanism of Figures 10 and 11 operates like any other 7 buzz saw to which the material is fed by a swinging table, and a detailed description of the operation is not necessary. Having thus described the invention, what is claimed is v The combination with a twin shaft gear assembly, such as a rear-wheel drivingmechav nism for an automobile, including an elon-' gated tubular axle housing, shafts journaled whereby such an assembly as a discarded and enclosed in the housing and extended beyond the ends of the housing, and a differential located between the ends of ,the' housing. and connecting the said shafts: of means rear-wheel driving 'mechanism, constructed as set forth, may be employed in the making of a. portable power plant, said means comprising a main vehicle frame, ground wheels mounted on the mainvehicle frameya substantially vertical auxiliaryframe fixed to the main frame to the rear of the ground wheels,

an engine on the main vehicle frame, a driving shaftconnected to the engine and to said differential, said, differential constituting means whereby power is transmitted from the vdriving shaft to one ofthe enclosed shafts, and constituting means whereby the housing and the enclosed shafts may be turnedin a substantially vertical plane transverse to the length of the vehicle frame, to cause the housing and the enclosed shafts to assume different angles, means for securing the housing fixedly to the auxiliary frame in at least two positions when the housing ashousing assumes any of said different angles, thereby to render said differential effective. to transmit power to the first-specified one of the enclosed shafts, and means on the first-specified one of the enclosed shafts for utilizing the power transmitted to it. Y

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
